Power Conductors

Development of eﬃcient power transmission is the need of the hour to alleviate the burgeoning demands of today’s power utilities system. Our Power Conductors are manufactured with a range of specialty alloys which oﬀer superior thermal resistance that improves the eﬃciency in high current transmission. As these new generation conductors enhance the current carrying capacity, they are favourable for use in reconductoring as well as new lines. This provides the user high corridor intensity and reduces congestion in existing lines.

STER - AAC

AAC conductor is also known as aluminium stranded conductor. These conductors consist of several layers of aluminium wires stranded concentrically. AAC are manufactured from electrolytically reﬁned aluminium with a minimum purity of 99.7%.

STER - ACAR

Aluminium Conductor Alloy reinforced (ACAR) is formed by concentrically stranded wires of Aluminium 1350 and high strength Aluminium–Magnesium-Silicon (AIMgSi) alloy core. The number of wires of each depends on the cable design. The typical design comprises a stranded core of AIMgSi alloy strands but in certain cable constructions, the wires of AIMgSi alloy strands can be in layers throughout the Aluminium 1350 strands.

STER - ACSR

Aluminium Conductors Steel Reinforced (ACSR), also known as Bare aluminium conductors, are one of the most widely used conductors for transmission. The conductor consists of one or more layers of aluminium wires stranded over a high strength steel core that can be single or multiple strands depending on the requirement. There can be various stranding combinations of Al and steel wires lending ﬂexibility to obtain suitable current carrying capacity and mechanical strength for the application.

STER - ACSRTM / AS or STER - ACSRTM / AW

Aluminium Conductors, Aluminium Clad Steel Reinforced (ACSR/AS or ACSR/AW) are concentrically stranded conductors with one more layers of hard drawn 1350-H19 aluminium wires on Aluminium Clad steel wire core. The core can be single wire or stranded depending on the size.

STER-ACCC

Sterlite Aluminium Conductor Composite Core (ACCC) conductor consists of a hybrid carbon and glass ﬁber core which is wrapped with trapezoidal shaped aluminium strands. The high strength structural core carries most of the conductor’s mechanical load, while the fully annealed aluminium strands carry all of the conductor’s electrical current. ACCC conductor’s composite core is much lighter and stronger than conventional or high-strength steel core.

STER-AL59

These are homogenous alloy conductors of Aluminium + Magnesium + Silica Alloy type. These conductors have a conductivity of 59% and hence have lesser DC resistance and higher current carrying capacity.
